mp3 player digital/optical linking to radio head unit

Has anybody thought of connection the optical out from your mp3-player (iriver h140 has this) on the digital link going from the CD-Changer to the head unit ?

If I understand well the CD-changer is connected via a digital (optical fibre) link to the main system.

Does anyone know if a digital input is available on the cd-changer ?

Would it be possible to wire the mp3 digital out to the same input slot as the cd-changer ?

This should result in the best possible data transfer, including no influence at all on the bass.

BMW most probably uses a proprietary technology on their fibre link. I don't think they use the TOSlink standard that your MP3 player is using.

Actually BMW uses an open standard called MOST.
Read more about it here:
TOSLink will not interop with MOST.
